okay, i'll be the one to take on the hated, unpopular, unpleasant role of suggesting that perhaps the difference in numbers is due to your squat depth. you can't fake deadlifts: you either pick it up or you don't. but you can certainly reduce depth in squats. are you 100% sure that this isn't the case? maybe your deadlift actually is higher than your legit squat number.

before you try to slice my throat, keep in mind that i haven't seen you squat, so i have no idea! consider posting vids of your lifts.
